Your friends are having a fun time with some trendy new Facebook app and you don't want to be the cranky curmudgeon that complains, but you also don't want to see their posts. What do you do? Block the app of course.

While this feature isn't particularly new, it can prove very handy if you're one of the growing number of people who don't like to see certain apps. To permanently end the flood of posts from a particular app, here's what you need to do:

Click the drop down menu attached to the post itself.

Select "Hide all from [app name]." (Note: if you're using the new interface, you may have to select "Hide" and then choose to block all from that app.)

Enjoy life.

If you ever need to unblock the app for whatever reason, you can undo it by going to your Facebook Settings and, under Blocking, removing the block on the app. Though, in certain cases, you may never even want to. This trick works for people too, as we've mentioned before, but we thought this was worth revisiting with the rise in certain apps.
